The advice I give to other kiters about kiting in westerlies over winter is because im concerned about their well being and ive seen a lot of crazy $hit happen and most of it is in westerlies.I started kiting 11 years ago and you really had to respect the kites you used then,hardly any depower.Kiting gusty westerlies then was just crazy.I didnt start kiting westerlies till 2006 ,kites had a bit more depower then but still 4 line C kites.Had some real scary times myself then. I use bridle kites now and only kite westerlies to 30 knts,not fun being overpowered waiting to get flogged buy a gust.
The kites now have heaps of depower, some even 100%

.
It gives learners a false sense of security because when the $hit hits the fan that kite isnt gunna be at 100% depower.
Agree with djdojo on all his points especially this
That is one stomach-churning video. IMO, kiting in any more than 35 real knots is for professionals or those with a death wish. I consider myself a pretty decent kiter and an experienced waterman but I have no interest in riding 40 knots, let alone 60. I've windsurfed in 40+ knots, but with kiting the risks are just too high for this little vegemite.
Windsurfing for me also above 30 REAL knots
